Answer:
there is a store in Antioc IL called AAA tactical Airsoft. I have airsofted for 4 years and this is the only airsoft specialty store i know of. i have also seen some decent guns for sale at a Walmart in McHenry county. this is not a joke. They had the cyber gun AK-47 Spetznaz and numerous other quality weapons. (scar l, mp7, etc.)
